Chapter 4. Using Memory & Communications Features
Introduction
Chapter 4 shows you how to use memory and communication features available on the meters.
Data Storage
The meter has three types of memory data: SAVE mode, LOG mode and COMP mode.
Undertake "clearing memory data" operation first if the date storage functions are used firstly.
The date storage mode is unavailable when the meter is in D.H, A.H, P.H, Hz% or MAX MIN function. The COMP
mode is unavailable when measuring capacitance. The range cannot be changed when the date storage functions are
active.
In MEM position, "- - - -"on the screen indicates data storage is empty and could save the data; "FULL" on the screen
indicates data storage is full and will stop saving.
In LOG or COMP mode, no data could be saved if there is a recording (no matter the storage is full or not).
The user should clear off the memory and then start to save. In LOG or COMP mode, the meter will return to measuring
mode when the storage is full.

SAVE Mode
Proceed as follows:
1. Press
to save reading, "MEM" appears in the display and record number is displayed in the secondary display,
the meter enters into SAVE mode.
2. Press
to save present value in the memory and the record number increments by one.
3. Press
for more than 2S or set the rotary switch to any other position to exit the SAVE mode.
LOG Mode
Proceed as follows:
1. Set the starting time and interval time of the real time data (see "Changing the Default Settings").
2. Press
, "LOG" appears on the screen and the recorded number appears in the secondary display; the elapsed
time display shows the time and the meter enters into LOG mode.
3. Press
to start log mode, and counts the time. On the starting time, the meter begins to store the data in the
Logging Saving Memory. The meter exits the mode automatically when the storage is full.
4. Press
for more than 2S or change the rotary switch position to exit the mode.
COMP Mode
1. Press
, "COMP" appears on the screen and the record number appears in the secondary display; the elapsed
time display shows the time and the meter enters into COMP mode.
2. Set the upper and lower limits. Press
in the primary display flashes. Press the blue button to select the set digits. Use
of the set digits. Press
that of the upper limit. Press for the third time to save the set data.
3. Press
to start COMP mode. If you do not undertake step 2, then the default values of the upper and lower limits are
